Title: Improvements in and relating to liquid fuel burning devices
IPC: F23D11/44
Filed: 1956-06-23
Abstract: 848,203. Vaporizers for liquid fuel burners. WYKES, F. Nov. 23, 1956 [June 23, 1956], No. 19509/56. Class 75(1). A vaporizer for a liquid fuel burner comprises a chamber having a fuel inlet, an electrical resistance for heating the fuel and a discharge nozzle for producing a high velocity jet for entraining the combustion air, the chamber having internal surfaces formed and arranged so as to be heated by the heater and to constrain fuel to follow a circuitous path during its travel through the chamber whereby it is gasified under pressure. In the form shown, fuel enters from a supply pipe 8 through a filter 36 which also serves to prevent pressure in the pre-heater forcing the oil back, and passes into the casing 37 in which is axially mounted a chamber 39 sealed from the casing and bearing partitions 40 which have segmental portions cut out alternately at diametrically opposite positions to create a sinuous path for the fuel. An electrical resistance 45 for heating the fuel is mounted in the chamber 39. From the end of the casing the fuel passes through a pipe 48 into a Venturi tube 47, air being drawn in by orifices 49 in the tube.

Title: A method of and apparatus for drawing glass tubes
IPC: C03B15/16
Filed: 1930-07-02
Abstract: 354,509. Making glass tubing. HADDAN, R., 31, Bedford Street, Strand, London.-(Corning Glass Works ; Walnut Street, Corning, New York, U.S.A.) July 2, 1930, No. 20111. [Class 56.1 Relates to a method of making glass tubing, particularly lens-fronted thermometer tubing having the bore backed by a coloured stripe. The invention consists in forming a narrow layer of coloured glass on a bath of molten clear glass, and in drawing a tube vertically upwards from the two glasses through a shaping device situated above a cooled nipple immersed below the surface of the glass. The glass from which the tube is drawn is contained in a pot 2, Fig. 5, housed in a -furnace structure 3 and filled from time to time with fresh glass by ladling through an aperture 4 in the roof of the furnace. A hollow nipple 5 is inserted in the bottom of the pot and is cooled, if required, by a jet of air from a pipe 6. The drawing mechanism consists of a pair of wheels situated above the roof of the furnace. A cylindrical casing or boot 10 is fitted in an aperture in the roof above the nipple 5, and its lower end supports a shaping-member 12 which dips into the molten glass and gives the required shape to the glass tube as it is drawn. A perforated pipe 15<1> surrounding the tube is supplied with air and enables the temperature within the boot to be controlled. In operating the device, the pot is filled with glass until its surface is above the lower edge of the shaper 12. Drawing is started with a bait and is continued by the drawing wheels. The shaper 12 gives the desired cross-sectional shape to the tube which is drawn from the cooled glass over the nipple 5. Air may be allowed to pass through an opening 27 in the head of the nipple. to maintain the bore of the glass tube. When a coloured stripe is to be inserted in the tube, the lower edge of the shaper is cut away at 14, Figs. 5 and 8, and a floating frame 17 is placed in contact with it. The floater is divided into two compartments 24, 26 by a transverse bridge 22, and slots 23; 25 are formed in the lower edges of the bridge and the wall 20 which is in contact with the shaper. Coloured glass is introduced into the compartment 24 and floats on the surface of the clear glass in the pot; and clear glass is introduced into the compartment 26. As the draw takes place, the coloured glass is drawn along beneath the surface of the glass in the compartment 26 and forms a coloured stripe '28 behind the bore. of the glass tube.

A chamber 17, through which air entering at 20 passes to the fan 18, extends over the passages 14, the air being made to contact with the passages 14 by baffles 21. Air also enters through apertures 19, passing through cavities in the side walls, where it is partially heated by radiation from the interior, to the fan. The air is delivered by the fan through a chamber 22 and apertures 22a, exhausting through damper-controlled openings 23 and also through pipes 24 whereby heat is carried into the preheating chamber 17. Baffles 25 direct the air on to the tea &c. on the trays.

Abstract: 525,605. Electrically-operated brakes. PHILIPS LAMPS, Ltd. July 15, 1939, No. 20659. Convention date, July 18, 1938. [Class 103 (i)] [Also in Groups XXXV and XL] The core of an electromagnet provided with an armature attracted by both ends of the magnet and a shading ring encircling a portion of one pole is divided into two or more portions so that the flux corresponding to the portion of the pole enclosed by the shading ring is kept separate from the remainder of the flux. Figs. 5 and 6 show the application of the invention to a radio tuning-device. The laminated core of the magnet consists of two parts 7 and 8 separated by a member 9 of non-magnetic material. The separation is continued by the shading ring 4. The armature of the magnet consists of a disc 13 rotated by the setting-knob 12. When the set is in tune with the desired wavelength a current passes through the coil 3 and attracts the disc 13, thus braking the setting-mechanism. The application of the invention to a brake for a gramophone is also described. The core may be divided into three portions, the middle one of which carries the shading-ring.
